Now Grouping is only for helping to hold object together, and for easy selecting. But it would be magic if Grouping to be able to create an instance! Like Components in Sketchup or instances in 3d max. So, if i model something by morph, copies of it can be modified by edit only one of them! Not for only morph. For any objects, that can be grouped.

Of course! But the fastest way to do it: 1. create model of necessary objects by morph or other 2. Store the original morph somewhere in the project 3. Save morphs and any other as GDL 4. Use any quantity of copies of this GDL object. 4. Edit the origin morph 5. Save edited morph as GDL (rewrite with same name). But, i think you understand how many limitations has this method. And MODULE has even more limitations. Unlike other architecture programs Archicad is on the way to make working process maximally free, intuitive and flexible. So in this way i say about block (like in AutoCAD), component/dynamic component (in Sketchup), instance (in 3d MAX). MODULE in the end, with edit-in-place function to reduce annoying extra actions. MORPH with instances ability. Or....just...Group command works like BLOCK in AutoCAD....

An instance / module / component manager and editing window similar to the detailing / worksheet windows where you could use all tools (3D and 2d) to create an object/ a room/ an apartment etc would be ideal.
Such a tool would simplify file management for projects in a similar way to when Plotmker was incorporated into ArchiCad. This tool would also likely meet the object creation needs of most users and not require them to delve into GDL.

Would be nice if saved Morph as GDL would be possible to edit in Library Part Editor directly - as it's possible to edit GDL script. In today's ArchiCAD you can create Morph, save it as a library part and place it as many time as you want, but routine is starting when you want to modify it: or you need to keep your initial morph somewhere on the plan (let say in special hidden layer). If the initial morph has been deleted - then it's necessary to convert the object to morph and re-save. If GDL object had drawn 2D symbol - you will need to draw it again after morph was re-saved. Everyone can agree with me - this routine is not so quick and simple as editing instance in Sketchup.

it would be better if there are features such as making components (in sketchup) this is certainly very helpful and speed up work. I hope that this feature will be as soon as possible, considering that the revit software also seems to have this feature already.
